Botox Side Effects
Botox has been studied totally in controlled trials. In these studies, the complications that happen in a bunch of folks taking the drug are documented and are then matched against side effects that happen in another group of folk not taking the medication.
This way, it is actually possible to see what side-effects happen, how frequently they appear, and how they compare to the group not taking the medication. In studies of Botox for cosmetic use ( to boost the appearance of lines between the eyebrows ), common complications included : * Droopy eyelids — in up to three % of people * Queasiness — up to three p.c * Muscle weakness — up to two p.c * Facial discomfort — up to two p.c * Indigestion or angina — up to one p.c * Tooth issues — up to one p.c * elevated blood pressure ( raised blood pressure ) — up to one p.c.
In studies of Botox for treating medical conditions instead of for cosmetic purposes, the following common Botox side-effects were reported : * Droopy eyelids — in up to 20.8 % of folk * Difficulty swallowing — up to nineteen % * Vertical misalignment of the eye ( vertical deviation ) — up to 16.9 p.c * Higher breathing infection ( e. G the common cold ) — up to twelve p.c * neck discomfort — up to eleven p.c * Headache — up to eleven p.c.
